DANIEL MCFARLJLN MOORE, OF NEW'ARK, NE'XF SERSE'?, ASSIGNGR TO MOGRE ELEC- TEICAL COMPANY, OF NEW YORK, N. Y., A CORPRATION GF NEW" Y FIXTURE AND REFLECTOR FOR VACUUM-TUBES.

To all flo/hom it may concern.'

Be it knoivn that l, DANIEL MOFARLAN Moonn. citizen of the United States, and a resident of Newark, in the county of Essex and `State of Nerv Jersey, have invented certain neiv and useful lnniroveinents in Fixtures and leliectors for Vacuuinfubes, of Which the following is a specification.

lily invention relates to fixtures for vacuuin tube lighting and is designed 'to provide a simple and convenient forin of fixture affording ineans for supporting the tube and a reflector and for also supporting, if desired, a conduit through Which a Wire, usually a high tension Wire, of the systein runs.

The fixture is, in the general forni, of a bracket and inay be either used as a hanging or ceiling bracket or as a Wall bracket, although it is more particularly adapted for use as a hanging iixture or bracket.

Generally speaking, iny invention consist-s of a bracket carrying a ring or other attachn'lent adapted to sustain a run of tubing and also provided, at its opposite sides, With a ledge, step or support adapted to sustain the opposed or meeting ends, respectively, of tivo sections of reliector over or in proper relation to the tube and so as to perinit a continnoi'is or practically continuous line of reflecting surfaces to be built up over the tube, as will. be hereinafter inore particularly described.

My invention consists further in the novel features of construction, hereinafter niore particularly7 described and then specified in the claiins.

in accompanying drawings ,-Figure l is an elevation of a fixture embodying niy invention taken froin one side thereof and of a construction or forni adapted to support a double run of tubing. Fig. 2 is a siniilar vierv of the fixture as used for a single run. Fig. 3 is an edge vieiv of the fixture shown in Fig. 2. Fig. 4 shows a nuniber of fixtures with the sections of rellector in place. Fig. 5 is a plan of the apparatus shown in Fig. 4, a portion of the saine being shown in horizontal section.

l is the body or stein of the fixture and 2 the flange of base by which it inay be fastened to the ceiling or other support. Generally, it is preferable to inake the stein portion in the forni of a rather thin plate, as seen in edge view in Fig. 2, in order that Specicaton of Letters Eatent.

the said steni niay not obtrude itself upon the eye of the observer looking at the lighting tube froin the side.

rlhrough the plate l, forming the stein, extends an opening S, as near to the base plate 2 as convenient. Said opening perinits the supporting in the fixture and near to the base, of an electric Wire conduit or pipe si, forming a protective inclosure' for the insulated Wire or conductor 5 running through said conduit and forining a portion, generally a high tension portion, of the systeni. ln seine cases, this opening 3 is not required, as, for instance, in the case Where the lighting tube runs out froin and back to a protective inclosure t5 and constitutes alone the high tension portion of the systeni that is exposed outside the conlines of the protective inclosure. The fixture likewise enibodics a ineans for attachmentof the supporting ring '7 or other device through which the vacuuin lighting tube S runs. For this purpose, the fixture has one or inore bosses or enlargements 9 near the lower end of the stein or standard l forined as a pocket With vertical boreto receive a stein or rod l0 of insulating niaterial which terminates in a head ll, wherein the ring 7 niay be fastened by a scrcrv or other suitable ineans.

t 'l2 is indicated a set screiv for fastening the ,stein or rod l0 in the socket.

The drawing, vFig. l, shows a double lixture adapted to support a double run of tubing' and, in this case, is provided With a cross ineinber 12:3 designed to strengthen the fixture.

Projecting froin the stein near its free extremity are lateral projections, ledges or other ineans for supporting the reflector' sections l-l. yhese ledges or projections, as shoivn in Fig. 2, and indicated at l5, extend laterally froin the fixture in opposite directions, so that the adjoining ends of the reflector sections inay be hung or supported from the lixture to constitute a continuous line of reflector disposed parallel to and over the lighting tube. The forni of these ledges or projections inay be varied, but l ordinarily prefer to dispose thein as indicated in Fig. 3, so that they Will directly support the trough-shaped reflector or backing thereof by its depending skirts or flanges 16.

ln a double run of tubing, it is desirable to extend the reflector, if but one reflector` is or bracket and employed, across the space over the tubes, and, in that case, intermediate ledges or projections, between the tubes, would not be required.

The reflectors themselves are preferably of the troughshape, indicated in Fig. 1, the distance between the skirt-s 16 being, in any case, determined by the distance between the two members of the double run of tubes and being shortened correspondingly if the skirts are intended to extend down to opposite sides of the same run or length of tube, as would be ordinarily the case, for a refiector used with a fixture, such as shown in Fig. 3. The reflector itself may consist of a sheet metal backing having a reflecting surface and a glass facing held in position by the turned over edges 17, of the sheet metal.

The ends of the trough-shaped sheet metal sections rest upon the ledges l5 and their ends being in close proximity, the practical effect of a continuous reflector, corresponding to the continuous tube of light, is obtained.

What I claim as my invention is l. A fixture for vacuum tube lighting provided with means for supporting a vacuum tube and with oppositely extending ledges or projections adapted to form supports for adjoining ends of sections of a sectional reflector built up into a continuous reflector over said tube.

2. A fixture for vacuum tube lighting having a stem or standard provided at its free end with means for attachment of the' 4. In a fixture for vacuum tube lighting, the combination of a -stem or standard provided with a flange or base for attachment to a ceiling support and with means for supporting a vacuum tube, and means for supporting a reflector built up in sections over the tube with adjoining ends of the sections meeting at and supported by said fixture.

5. A xture for vacuum tube lighting having a stein or standard in the form of a plate provided with a boss or enlargement having' a vertical bore or socket and with ledges extending in opposite directions from the plane of the plate to form supports for a sectional reflector' continued over the line of tubing, as and for the purpose described.

6 A xture for vacuum tube lighting having two oppositely projecting ledges projecting therefrom in the direction of the axis of the tube and inclined downwardly in a direction transverse to the said axis of the tube and adapted to support the juxtaposed ends of the sections of a .troughshaped reflector by the flanges or sides of the trough.

7. A fixture for vacuum tube lighting consisting of a hanging bracket having a transverse perforation for receiving a wire conduit, a vertical socket for receiving the stem which carries the tube support and with means for supporting the meeting ends of the sections of a sectional reflector extended longitudinally over the tube carried by the fixture.

8. A fixture for Vacuum tube lighting having means for supporting a vacuum tube and provided with means for sustaining the juxtaposed ends of sections of a reector extended as a continuous reflector over the tube.
